Implementation description

Factory Method Pattern

This project uses the factory method pattern, which defines an interface for creating an object, but let subclasses decide which class to instantiate. This application has the following participants:

• Product: Customer
• ConcreteProduct: Business, Returning, Frequent, New, VIP
• Creator: Factory
• ConcreteCreator: CustomerFactory

Software Design Principles

• Flexibility: Creating objects using factory method is more flexible than creating an object directly.
  • ConcreteCustomer objects are created at runtime, which adds flexibility.
  • Future products (i.e, type of customer) can be added by simply implementing the Customer interface.
• Modularity: This application is divided into well-defined parts - creator and product.
• Cohesion: Like-minded class are grouped together. For example, Business, Returning, etc. are in the product package.

How to create a binary runnable package

mvn clean compile assembly:single

How to run

mvn -q clean compile exec:java -Dexec.executable="edu.bu.met.cs665.Main" 

Run all the unit test classes.

mvn clean compile test checkstyle:check  spotbugs:check

Using Spotbugs to find bugs in your project

To see bug detail using the Findbugs GUI, use the following command "mvn findbugs:gui"

Or you can create a XML report by using

mvn spotbugs:gui 

or

mvn spotbugs:spotbugs

mvn spotbugs:check 

check goal runs analysis like spotbugs goal, and make the build failed if it found any bugs.

For more info see https://spotbugs.readthedocs.io/en/latest/maven.html

SpotBugs https://spotbugs.github.io/ is the spiritual successor of FindBugs.

Run Checkstyle

CheckStyle code styling configuration files are in config/ directory. Maven checkstyle plugin is set to use google code style. You can change it to other styles like sun checkstyle.

To analyze this example using CheckStyle run

mvn checkstyle:check

This will generate a report in XML format

target/checkstyle-checker.xml
target/checkstyle-result.xml

and the following command will generate a report in HTML format that you can open it using a Web browser.

mvn checkstyle:checkstyle

target/site/checkstyle.html
